As with previous problem, please upload a Ranorex snapshot (not screenshot) of the problematic element.

In some cases, recording may not record certain elements properly (combo boxes, context menus and similar elements). In these cases, you may need to use instant tracking feature.

But as mentioned, it's hard to tell what's wrong without seeing, at very least, a Ranorex snapshot. And once again, Ranorex 6.2 is way too old and no longer supported. Please try to reproduce your problem with latest Ranorex 8.0 or previous 7.2.1 (even in trial mode).

OK, the SetValue action, shown in your previous post, has been recorded by Ranorex or you added it manually? I guess it was added manually, right?

You see the 'null' value in SetValue action, because the drop-down has most probably not been expanded at a time of adding the SetValue action and associating it with the Select tag from repo. In other words, the list of options is not loaded in memory and therefore, Ranorex cannot display the list of available options for the given Select tag. If you insist on using SetValue action, you will have to enter the TagValue manually.
